could you please explain how to take symmetry boundary condition

 

The fluid flow and heat transfer simulations have been carried

out using commercial CFD tool, ANSYS CFX 14.5. The

coolant used in the experiments is water and the same is used

in CFD studies for validation and parametric studies. A single

phase laminar fluid flow and heat transfer analysis is carried

out. Continuum flow is assumed inside the micro heat exchanger.

The flow field and heat transfer characteristics through the

micro channel heat sink are obtained by solving the threedimensional

governing equations namely the following: continuity

for conservation of mass, Navier-Stokes equation for

conservation of momentum and energy equation. Fluid

domain of water and solid domain of micro-channel heat sink

are meshed separately and proper interface is defined in

ANSYS CFX Pre for capturing the flow physics. The meshing

of fluid and solid domains is carried out in ICEMCFD tool

using blocking methodology. Only one fluid channel and two

solid domains, each half on either side of the fluid domain,

are considered in the analysis and the entire model with 122

channels is not simulated. Symmetry boundary condition is

applied on either side of the solid domains of the MCHS

assembly.

Hello Mahesh,

You can search in Youtube" on simulation of heat transfer and fluid flow in heat sink using ANSYS FLUENT". You will get the right tutorial which explains step by step procedure from geometry to post processing.
 Please note that the tutorial is not prepared by ANSYS.

Hope you get the right tutorial and helpful to you.
